Serial No. 140,592.

To all wlw/m. may conce/11n.'

Be it known that l, EDWARD Gr. SGHRIEFER, a citizen of the United States, residing at Cincinnati. in the county ot Hamilton and. State ot Ghio, have invented certain new and usetul improvements in Extensible Cases, of which the following is a speciiication.

My invention relates to improvements upon the extensible cases shown, described and claimed in my applications for Letters Patent of the United States, Serial ros. 92460, 92Ll61, 924552 and 92463, all tiled February 3, 1902, tor extensible cases, and my invention consists in new and improved construction of door and means for forming a composite door out of several doors of superposed sections; in new and improved means ot constructing the base and top ot an extensible case tor providing clearance at top and bottom for the door to swing, in new and improved means for holding the door in closed relation and locking the same in that position; in new and improved means for positioning a shelf with relation to the doors; in new and improved means bet' een sections for compensating for shrinkage or eXpansion of material, and providing for proper relative swinging of the doors; in new and improved means tor connecting superposed sections' and in the parts, and in the construction, arrangement and combinations of parts hereinafter more fully described and claimed.

In the drawings: Figure 1 is a perspective view ot my improved device showing one door swung open and partly exposing the in erior of the case, and partly broken away to show details ot construction. Fig. 2 is an enlarged vertical cross sect-ion of my improved device, t-alfen on a line corresponding to the line co-w of Fig. 1, partly broken away, showing the means for connecting superposed door-sections, and for providing clearance at top and bottom of the combined door, and means for compensating between sections for shrinkage or variation of material. Fig. 3 is perspective view partly broken away showing the connection between superposed case-sections and between superposed door-sections. Fig. i is front inside elevation sliowii'ig the connecting means between superposed door-sections ot my improved device, with tlie door-sections partly broken away. Fig. 5 is a plan view of the saine. Fig. 6 is a longitudinal section taken on the line e-e of Fig. 7 showing the pull and loclr in connection witi the door stile. Fig. 7 is a front elevation oi the same. Fig. 8 is a detail showing the relation ot the top board and side ot the base-section, and showing the side catch between the base-section and a case-section in side elevation, with said top board in cross-section on the line "J-g/ of Fig. 10. Fig. 9 is a detail ot the same in section on a line corresponding to the line ccf-:c of Fig. 8. Fig. 10 is a plan view of the same. Fig. 11 is a detail in front elevation showing one end of the top-section and a case-section, partly brolren avay, to show the manner of constructing the same and the relation ot the parts to each other. Fig. 12 is a bottom view, partly broken away, showing adjoining ends ot adjoining casesections, and showing the manner ot hinging the doors, and my improved pull for opening the doors, the pull permitting the outer ends of the doors to be moved past each other in opening without permitting catching of the doors one on the other, the means 'for holding the doors in closed relation and locking the same in that relation, and means tor positioning the shelf with relation to the door. Fig. 13 is a view in per pective partly broken anf'ay showing the manner of constructing the base for receiving a case-section and the clearance for the bottom of the door. Fig. 14 is a view in perspective of the spring catch for holding the door closed. ig. 15 is a perspective view of the protecting hook taking over the catch. Fig. 16 is a detail partly broken and in end elevation showing the locking plate connection with its door stile. Fig. 17 is a front inside elevation of the same. Fig. 18 is a detail showing the hinge in spread relation connected to a side and door. Fig. 19 is a detail in cross-section on the line fv-fv of Fig. 12 showing the manner of hanging and positioning` the shelf.

A represents the top-section or my i1nproved device, B B B2 the case-sections, and C the base-section. The top-section consists preferably of sides 1 2, a top 3, back Ll, and front (See Figs. 1, 2 and 11.) The inside front edges of the sides 1 and 2 are provided with rabbets 6 for receiving the front 5 leaving the reduced projections 7, S of the sides show at the front or" the topsection in the form ot a molding of a width to correspond with the width ot the exposed reduced projections of the sides ot the casesections hereinafter described. The lower edge 9 of the front 5 is in a plane above the lower edges 10 of the sides sothata clearance 151 is provided at the top of doors of casesections when the sections are superposed, in manner hereinafter explained. This clearance and the rabbet 6 also permits the hinged inner side edge of the door to project into the horizontal plane of the top-section if the combined height of superposed doors should be'greater than the combined height of superposed sides of case-sections. The casesections comprise preferably the sides 11 12, back 13, and doors 14 15. The base-section comprises preferably the sides 16 17, top boardl 18, back 19, and front 20.

One end ofeach side ofthe ease-sections, preferably the upper end, has a tongue 21 and the other end thereof, preferably the bottom, has a groove 22 extending short of the front edges of the sides, the tongue being preferably a separate strip secured in the groove 23, with the groove 22 of substantially greater width than the tongue for allowing clearance between v the tongue and side walls of the groove for permitting ready seating of the sections one on the other and allowing forshrinkage and variation. (See Figs. 1, 2, 3 and 1.2). The bottom edges of the sides 1 and 2 of the top-section also have grooves 22. Near its front edge each side of= the case-sections is provided with a dowel 24, preferably in its top, while preferably its bottom has a dowel-hole 25, theY dowel and dowel-hole having a closeV fit for positioning superposed sections at their front edges. The base-section also has a dowel 24 at each side and the top-section a dowelhole 25 at each side in the vertical plane of the dowels and dowel-hole of the case-sections so that any ofthe sections maybe placed one abovel another with the front edgesregistering,mak-V ing the sections interchangeable. The tongue preferably meets the doweland the groove tions rabbets 28 29 are provided, leaving front projections 30 31, in the form of a molding, of. a widthv preferably of the front projections 7 8, of the top-section. Y (Figs. 1, 3, 11 and 12). The inner side walls 32 of said frontvprojection of the topsection and: the `inner side. wall-33 of-said: frontpro-V jection ofthe case-section. areshown in a vertical'` plane one above the other... (See Fig. 11). The doors of the case-sections swingr on hinges- 34 in upright positions, the

hinges being secured to the doors and the 1 sides, the vertical planes of the hinges being near the vertical planes of the dowels at the respective sides. rThe hinges are preferably loose-pin butt hinges (see Fig. 18) comprising the butts 35 36, secured respectively to the side and door, and loose pin 37 taking through the knuckles 38 of the butt 35 and the knuckles 39-of the butt 36, the lower edges l40 of the'knuckles 39A resting on the upper edges- 41 of the knuckles 38, so as to position the lower edges of the doors flush with the lower edges of the case-sections, and having the clearance 42 between the upper edges 43 of the knuckles 39 and the lower edges 44 of the knuckles 38- for permitting the door-seetions toaccommodate themselves vertically upon the pins of the hinges should the combined superposed door be of greater height than the combined height of superposed sections, the eXtra height of door finding accommodation in the clearance 151, the construction being such also that accidental lifting of the door olf its hinges is prevented. The d`oor-sections at theirhinged edges are also provided with outer rabbets 45 for permitting the doors to swing open a greater distance. (See Figs. 3 and 12). The rabbets 28 29 form recesses into which the edges of the doors may swing, the inner corners of the rabbets forming shoulders 4'3V (Figs. 12 and 18) against which the inner edge of one buttof the hinge may take, the inner edge of the other butt of the hinge` being flush withl the inner face 47 of the door. The hinges are let into recesses 48 in the hinged edge4 of the door. TheV recesses are suthciently deep to accommodate both, butts of' the hinges. This construction of doorhanging insures ease and accuracyin hanging the doors so that superposed doors may have their hinges accurately one above the other.

Respectively the top and bottom of the door are provided with an inside rabbet 49 and-, an outside rabbet 50, or vice versa, (Figs. 2, 3', 4, 5 and 12) so as to provide adjoining side faces 51 52 and top and bottom meeting faces` 53 54, and inner and outer reduced projections 55 56 for superposed doors when arranged in superposed positions.

In order to connectV superposed sections of,l doors I' provide a door catch D (Figs. 1, 2, 4 and 5') comprising a swingable lever 57 pivoted on a rivet 58to a. plate 59 secured to one door-section and having a flat shank 60 taking under a lip 61 struck up from a plate `G2 secured to the meeting end of the doorsection above. rllhevlip is resilient and the lshankis snugly held and yieldinglypressed@ betweenthe lip and plate. vThe edge ofthe lip is.- provided with a. series of preferably.v

Cit

concentric contact yfaces G3 eccentrically' arranged with relation to the pivot of the lever. The outer end of the lever has a lug G4 at its side struck outwardly for forming a flat grip for the lever extending longi tudinally of the lever. A shoulder 6G on the lever takes against said contact faces, which, being consecutively arranged farther from the pivot of the lever, draw the sections of doors toward each other. The shoulder is adapted to rest in seats 67. The top face 53 and the lower face 54 of superposed doorsections are thereby clamped together, the lever spanning' the meeting faces of the doorsections and preventing relative sidewise movement of the door-sections, the reduced projection 55 of one door-section being rigidly held between reduced projection 56 of the other door-section and the lever, as shown in F ig. 2. The door-sections are thereby clamped vertically and laterally for forming a rigid united door. In practice this construction of the door-sections and their connections practically form a solid door.

lood, which is subject to shrinkage and variations in dimensions from time to time, is a material out of which my improved eX- tensible case may be made, and my improved construction is such that these variations will not detrimentally affect the operation or construction of the parts, provision being made for accommodating such change's. The dowels, being near the front edges of the sections, position those front edges irrespec tive of what sections are superposed so as to assure the pintles of the hinges of superposed case-sections to be one above the other, and there being such little material between the dowels and hinges, there is substantially, in practice, no variation in relative position between the dowels and hinge-positions. T he grain of the wood of the sides of case-sections usually runs lengthwise of 'those sides. T he dowels form the fixed points from which shrinkage and variation take place, and the relatively wider grooves at Lne sides and back permit shrinkage and variation of the major part of the case while the tongues in the grooves act dust-strips. rlhe elearance 151 and the clearance between the butts of the hinges also permit the doorsections to be made slightly higher than the sides of case-sections, if desired, while the projections 55 55 act as dust t strips with suiiicient lap for allowance for shrinkage or variation, the said clearance also permitting the door to project into it in case of swelling' of the door.

In order to provide for proper lapping of the doors at the middle when the case is closed I provide one of the doors with an outside rabbet 71 and the other door with an inside rabbet 72 for forming lips 73 74 between the doors. (See F ig. 12.) In my ini aroved construction therefore the doors have an inner reduced projection at one vertical end and an outer reduced projection at the other vertical end, while the right-hand door has an inner reduced projection at one side and an outer reduced projection at its other side, the left-hand door having an inner reduced projection at both sides. (See Figs. 2, 3 and 12).

In order to insure closing of the doors at various positions at which a shelf may be placed vertically of the door I provide the door with a rod 75 secured thereto by screws 7 6 taking through apertures in the rod and ferrules 77 and screwing into the door-stile, the rod extending up and down lengthwise of the door-stile. The mating doors of a given case-section of a case may each be provided with a rod of this kind while the doors of the remaining case-sections may be free of this rod, the one pair of rods with their springs and catches to be presently described being suflicient to hold closed the composite door when the various sections of the door are connected. (See Figs. 1 and l2.) A spring-catch F comprises a spring-plate 78 having suitable spring lingers 79 80 projecting therefrom for receiving the rods when the doors are closed. A hood 81 takes over the spring lingers for protecting the same and preventing4 injury therefrom, the hood being provided with transverse slots S2 into which the rods may pass into engagement with the spring lingers, the corners and edges of the hood being` rounded. Spring fingers with their plate and hood are suitably secured to the shelf as by means of screws S3. The screw 83 passes through a hole Sil in the hood and a hole S5 in the spring plate. The shelf also carries a hoolr SG pivoted preferably at its bottom as on a screw 87, and is adapted to take about one of the rods for holding one of the doors closed against outward pull. The other door is provided with a lock 8S, the bolt S9 of which is adapted -to take in rear of a plate 90 in an undercut channel 91 at the bottoni of a recess 92 in lip 73, a screw takin through a slot 94 in plate 90 into the lip for adjustably oositioning` the plate 90 with rolation to the edge of the lip so to project a greater or less distance beyond the lip for receiving the bolt in case of variations in distance between doors. (See Figs. 12, 16 and 17 rl'he spring-fingers and hood and hook are carried with the shelf as the latter is raised and lowered inthe and are adapted to act on the rod throughout various elevations of the shelf so that the door may be releasably closed throughout the various elevations and also locked throughout those elevations. rhe plate 78 has an upwardly pressed part 9o upon which the spring-finN gers are secured for raising the yokes 96 of the spring fingers into vertical line with the inner walls 97 of the apertures 82.

E represents the shelves for supporting which I provide means similar to the shelf supports shown, described and claimed in my application Serial No. 105388, filed April 30, 1902, for adjustable shelf supports, upon which my present construction is an improvement in eXtensible cases. I provide shelf strips 101 102 at front and rear of each side of the case-sections sunk into said sides, and having openings 103 into which hooks 104 of shelf-supports 105 take for hanging the shelf-supports on the strips. The shelfsupport at its front end has an upwardly projecting outwardly inclined lip 106 having a front contact face 107 and a rear contact face 108. rIhe bottom of the shelf at each end at itsfront portion is provided with a slot 109 over which a plate 110 provided with a slot 111 shorter than the latter slot is adapted to be secured, as by screws 112, 113 taking through slots 114 115 in the plate 110 and 'into the shelf. The slot 111 has a front wall 116 and a rear wall 117 for contacting with the faces 107 108. Movement of the hook 104 in the opening 103 is limited by the side edges of the hook contacting with the ends of the opening. The plate and lip position the front of the shelf with relation to the front of the case-section for determining the position of the spring-fingers, so that those fingers may be accurately placed for receiving the rods of the doors and holding the doors closed in proper' position. The rear of the shelf stops short of the rear of the case-section, leaving a clearance 118 for permitting the rear of the shelf to freely osition itself according to the shrinkage of the wood that may take place; The shelfsupport is also preferably provided only at its front end with a lip 106, the rear of the shelf-support preferably being without the lip, with the rear of the shelf resting on the ledge 119 of theshelf-support.

In order to permit the outer edges of the doors to swing past each other freely when the cases are arranged in lateral extension and at the same time provide convenient means for opening the doors I have provided a door of each case-section with a pull 121 having a bulged portion 122 and shank 123 through which shank screws 124 passv into the door stile for securing the pull to the door. (See Figs. 6, 7 and 12). The door stile is also provided with a recess 125 projecting under the pull and past the bottom of the pull, for greater freedom in admitting the finger under the pull. he bulged portion of the pull has the sloping sides 126 127, meeting the door stile and permitting the stile of the door of the adjoining section to slide upon the outer surface of the pull without danger of injury of projecting points. The shank is provided with horns 128 129 forming a rounded upper end 130 taking snugly about the rounded outer end of the tube 131 of lock 88.

For further securing the sections together when arranged in vertical extension I provide the improved side catch G (see Figs. 8, 9 and 10) comprising the lever 132 pivoted on a rivet 133 on a plate 134 secured to one section, the lever lapping the next section and taking under a lip 135 struck up from the plate 136, the lever being snugly held between the lip and plate and yieldil'igly pressed therebetween, the lip having resilient properties. These side catches are secured and operated within the planes of eX- tension of the sides, being located in recesses 137 138 respectively at the top and bottom of the sides of sections. The lip 135 is prof vided witha series of contact-faces 139 eccentrically arranged with relation to the pivot of the lever,y the lever having a lug 140 at its side struck outwardly for forming a fiat lengaging surface for operating the lever," a contact face 141 on the lever engag ing the faces on the lip for drawing superposed sides toward each other and keeping them in drawn relation from the inside `of the case, the lever spanning superposed sections.

A lug 142 isprovided for limiting retraction of the lever in such position that the lever, when retracted, may rest practically flush with or below the edge of the section to which it is secured or the upper edge of the plate 134. The contact face 141 is adapted to rest in seats 155 in the lip 135. Similar catches also connect the top-section and a case-section to the base-section. rlhe top board 18 of the base is provided with a slot 143 through which the lever 132 projects, and in which the plate 134 lies, the plate being secured below the top board byl the nails 144 to the inside of the sides 16 17 in recesses 137 in those sides. (See also Fig. 13). Thel top face of the top board 18 has its side edges provided with recesses 145 inside the side rabbets for admitting the finger or thumb for raising the lever. The top board of the base-section is provided with side rabbets 146 147 and a rear rabbet 148, the lower faces of which are of substantially similar elevation, the front of the base being provided with a deeper rabbet 149. (See also Fig. 2). The base is also provided with dowels which are located in said rabbets 146 147, and the lowest case-section is adapted .to rest on the lower faces of the rabbet's at the side and rear of the base-section, the rear rabbet being sufficiently wide to allow a'. clearance 150 to accommodate shrinkage or variations of material. As.`

already'explained clearance 151 is provided door Without binding. The upper reduced f l nroieetion 5@ of the door takes a 'ainst the "i J l n (j vi 1 troni, f on oi ine top-section and the lower reduced -)ro ection oi the lowest A 'i C 1 v J l door `es against the iront tace infr at the base-section- Oyeiiapninn is thus irovided ,`|l Q I. l l between the doors and inside or the case ai top, bottoni sides for arresting dust 1rrespective of the height of tre combined doors. Will be noticed that tne front face is projected io Wardly distance corresponding to the Width of the rabbet in the top of trie top-section ot the door so that the tron-t n races 154.-

in different yertical planes.
